Howard C. Hopps
1986, Science of Total Environment (54) 207-216
The emphasis on harmful substances that may occur in potable waters has almost obscured the fact that important beneficial constituents are commonly present.The chemical substances in water that make positive contributions to human health act mainly in two ways: (i) nutritionally, by supplying essential macro and micro elements that the...

Michael E. Nelson, L. David Mech
1986, Journal of Wildlife Management (50) 691-698
Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (< 1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥...

James A. Estes, Karen E. Underwood, Margit J. Karmann
1986, Journal of Wildlife Management (50) 626-636
Daily time budgets and activity patterns of sea otters (Enhydra lutris) were determined by scan sampling at 4 study areas in central California. Diet was determined by direct observation of foraging animals. Average time invested in foraging ranged from 11 to 71% among viewing areas (1-2 km of coastline) and...

Herbert S. Garn
1986, Journal of the American Water Resources Association (22) 745-751
The lower 4 miles of the Red River, a tributary of the Rio Grande in northern New Mexico, was designated as one of the “instant” components of the National Wild and Scenic River System in 1968. The Bureau of Land Management (BLM), as the managing agency of the wild and...
Slip deficit on the San Andreas fault at Parkfield, California, as revealed by inversion of geodetic data
Paul Segall, R. Harris
1986, Science (233) 1409-1413
A network of geodetic lines spanning the San Andreas fault near the rupture zone of the 1966 Parkfield, California, earthquake (magnitude M = 6) has been repeatedly surveyed since 1959. In the study reported here the average rates of line-length change since 1966 were inverted to determine the distribution of interseismic slip...
Development and evaluation of habitat suitability criteria for use in the instream flow incremental methodology
Ken D. Bovee
1986, Report, Instream Flow Information Paper #21
The Instream Flow Incremental Methodology (IFIM) is a habitat-based tool used to evaluate the environmental consequences of various water and land use practices. As such, knowledge about the conditions that provide favorable habitat for a species, and those that do not, is necessary for successful implementation of the methodology. In...
Introduction to stream network habitat analysis
John M. Bartholow, Terry J. Waddle
1986, Report
Increasing demands on stream resources by a variety of users have resulted in an increased emphasis on studies that evaluate the cumulative effects of basinwide water management programs. Network habitat analysis refers to the evaluation of an entire river basin (or network) by predicting its habitat response to alternative...

1986, Journal of the American Veterinary Medical Association (189) 1006-1010
Of 39 captive whooping cranes (Grus americana), 7 died during a 7-week period (Sept 17 through Nov 4, 1984) at the Patuxent Wildlife Research Center, Laurel, Md. Before their deaths, 4 cranes did not develop clinical signs, whereas the other 3 cranes were lethargic and ataxic, with high aspartate transaminase,...
Recovery of compacted soils in Mojave Desert ghost towns
Robert H. Webb, John W. Steiger, Howard G. Wilshire
1986, Soil Science Society of America Journal (50) 1341-1344
Residual compaction of soils was measured at seven sites in five Mojave Desert ghost towns. Soils in these Death Valley National Monument townsites were compacted by vehicles, animals, and human trampling, and the townsites had been completely abandoned and the buildings removed for 64 to 75 yr. The soils studied...
The temperature dependence of isothermal moisture vs. potential characteristics of soils
J. R. Nimmo, E.E. Miller
1986, Soil Science Society of America Journal (50) 1105-1113
A method has been developed for rapid, transient measurement of hysteretic soil-moisture characteristics as a function of temperature. While a varying soil-water pressure was imposed on a thin sample by means of flexible membranes held in firm contact with the soil, water content was measured by gamma-ray attenuation, and matric...
Theory, construction and operation of simple tensiometers
David I. Stannard
1986, Groundwater Monitoring and Remediation (6) 70-78
The tensiometer, introduced by Richards and Gardner (1936) has been a tool often ignored in unsaturated zone investigations. Hazardous waste disposal studies that require values of unsaturated zone matric potentials will expand tensiometer use. Familiarity with operation and installation principles is necessary to ensure quality data collection.The essential elements of...

Correlations between stream sulphate and regional SO2 emissions
R. A. Smith, R. B. Alexander
1986, Nature (322) 722-724
The relationship between atmospheric SO2 emissions and stream and lake acidification has been difficult to quantify, largely because of the limitations of sulphur deposition measurements. Precipitation sulphate (SO4) records are mostly <5 yr in length1 and do not account for dry sulphur deposition2. Moreover, a variable fraction of wet- and dry-deposited sulphur...

he neutron borehole logging tool was calibrated for the determination of moisture content in theunsaturated zone of an alluvial aquifer. A continuous core sample was collected to a depth of 15 ft from the unsaturated zone.Moisture content and other soil properties were determined by standard soil-laboratory techniques. The neutron logs profile was correlated...

Richard L. Reynolds, Mark R. Hudson, Ken Hon
1986, Journal of Geophysical Research B: Solid Earth (91) 9599-9613
Rocks of the 23.1‐m.y.‐old Lake City caldera consist of the compositionally zoned Sunshine Peak Tuff, postcollapse intracaldera lava flows, and resurgent quartz syenite intrusions. Declinations of reversely magnetized (I = −45° to −75°) Sunshine Peak Tuff change from easterly (D = 93°–130°) throughout most of the tuff to southerly (D = 195°–207°) within...

1986, Conference Paper, Proceedings of the Third Caribbean Islands Water-Resources Congress
Water has become a critical commodity in the Caribbean Region. In spite of a relative abundance of rainfall even on the smaller islands, the region is faced with severe seasonal shortages as well as increasing water quality problems. The supply of thewater needs in the area will become even more critical...

Voyager 2 images of the southern hemisphere of Uranus indicate that submicrometersize haze particles and particles of a methane condensation cloud produce faint patterns in the atmosphere. The alignment of the cloud bands is similar to that of bands on Jupiter and Saturn, but the zonal winds are nearly opposite....
Changing landscapes and the cosmopolitism of the eastern Colorado avifauna
Fritz L. Knopf
1986, Wildlife Society Bulletin (14) 132-142
The avifauna of continental North America has changed dramatically since colonial times. Excessive hunting contributed, at least in part, to the extinction of birds such as the great auk (Pinguinus impennis) and passenger pigeon (Ectopistes migratorius), while more recently organochlorine insecticide residues have resulted in drastic reductions in numbers...

1986, Archives of Environmental Contamination and Toxicology (15) 367-376
The effects of environmental contaminants on the reproductive success of olivaceous cormorants (Phalacrocorax olivaceus), laughing gulls (Larus atricilla), and black skimmers (Rhynchops niger) nesting in Galveston Bay, Texas were investigated from 1980 through 1982. Populations of cormorants and gulls have remained stable in recent years, but skimmer numbers may have...

An assessment of ground-nest depredation in a catastrophically disturbed region, Mount St. Helens, Washington
Douglas C. Andersen, James A. MacMahon
1986, The Auk (103) 622-626
The explosive eruption of the Mount St. Helens volcano on 18 May 1980 severely affected a large ar- ray of plant and animal populations (Edwards and Schwartz 1981, MacMahon 1982, Wissmar et al. 1982) over a vast area (>600 kM2) (Fig. 1). Volcanic eruptions are relatively common agents of large-scale...
